Abstract
The utility model discloses a pressure-sensitive double sided tape which comprises a base material layer. An acrylic glue layer and a polyurethane adhesive layer are coated on the upper surface and the lower surface of the base material layer respectively, a first releasing material layer is pasted on the other surface of the acrylic glue layer and comprises a PET (polyethylene terephthalate) film and a PE (polyethylene) film, the PE film is laminated on one surface of the PET film, a silicon oil layer contacting with the acrylic glue layer is arranged on the other surface of the PE film, a second releasing material layer is pasted on the other surface of the polyurethane adhesive layer and comprises a PET film and a PE film laminated on one surface of the PET film, and a silicon oil layer contacting with the polyurethane adhesive layer is arranged on the other surface of the PE film. The pressure-sensitive double sided tape has stretch resistance and high stiffness, particularly, the probability of tearing the large-area double sided tape can be greatly reduced, so that operators can conveniently perform construction, and pollution to the glue layer is avoided.
Description
Technical field
The utility model relates to a kind of double coated pressure-sensitive adhesive tape, belongs to the bonding technique field.
Background technology
The products such as glass, sheet metal, plastic plate and electronic product are in carrying and use procedure, and its table and be subject to easily contact stain(ing) or polishing scratch and scratch usually adopts protective membrane to cover its surface and makes it to avoid damage and pollute.Double sticky tape in the protective membrane is owing to be widely used in electronics, computer, household electrical appliances, in the field, along with the development of electron trade, in order to reach required structure and assembling effect, the prior art combination only forms material requested stacked adding merely as required in assembling process for it, the upper and lower surface of face adhesive tape is bonded with respectively release film and protective membrane, during use, the protective membrane of tearing first is bonded in by bonding position, and then remove release film, stick on another by on the bonding position; Make two to be bonded together by bonding position.
Summary of the invention
The utility model provides a kind of double coated pressure-sensitive adhesive tape, and this double coated pressure-sensitive adhesive tape has stretch-resistance, deflection is strong, especially can greatly reduce the probability of tearing in the large area two-side adhesive tape, thereby the handled easily personnel construct and avoid glue-line to pollute.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double coated pressure-sensitive adhesive tape, comprise a substrate layer, and the upper and lower surface of this substrate layer is coated with respectively acrylic glue layer, polyurethane adhesive layer; Described another surface label of acrylic glue layer is covered with the first separated type material layer, and in the PE film on PET film one surface, this another surface of PE film has the silicon layer that contacts with described acrylic glue layer to this first separated type material layer by PET film and film;
Described another surface label of polyurethane adhesive layer is covered with the second separated type material layer, and in the PE film on PET film one surface, this another surface of PE film has the silicon layer that contacts with described polyurethane adhesive layer to this second separated type material layer by PET film and film.
Further improved technical scheme is as follows in the technique scheme:
1. in the such scheme, described PET film thickness is 0.012 millimeter-0.05 millimeter, and the thickness proportion scope of described PET film and PE film is 1:0.027～0.5.
2. in the such scheme, described substrate layer is film layer or layer of polypropylene foil or laminated polyester film.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model double coated pressure-sensitive adhesive tape has stretch-resistance, deflection is strong, especially can greatly reduce the probability of tearing in the large area two-side adhesive tape, thus handled easily personnel construction and avoid glue-line to pollute; Secondly, an acrylic adhesive layer is fit to the applying of general material, steel plate for example, the materials such as acrylic board, an ammonia ester gum adhesive layer shows activity and the polarity of height, with the base material that contains reactive hydrogen, such as porous materials such as foam, plastics, timber, leather, fabric, paper, potteries, and the material of any surface finish such as metal, glass, rubber, plastics has good chemical adhesive power.
